Table 1 compares the (CER) result of our model on the Aishell-1 test dataset with a few public models include: Espnet[1]}, WeNet[2]}, K2[3]} and
Neural Transducer+LFMMI[4]}. The first three models are all AED model structures, and the last is NT based. All our evaluation results round up to 2 digit after decimal point.
From Table 1, we can see that our proposed Base-WSOLB model is better than previous three AEDs model, but it is still a little worse compared with the NT model. In the experiment, we additionally learn that the effect of adding softmax to Base WSOLB became worse. This case may indicate that the fixed sum of coefficients is not effective.
